Where does the word homework come from?

Mentions of the term “homework” date back to as early as ancient Rome. In I century AD, Pliny the Younger, an oratory teacher, supposedly invented homework by asking his followers to practice public speaking at home. It was to help them become more confident and fluent in their speeches.

Is logical an operator?

A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.

Which is the highest precedence operator?

The logical-AND operator ( && ) has higher precedence than the logical-OR operator ( || ), so q && r is grouped as an operand. Since the logical operators guarantee evaluation of operands from left to right, q && r is evaluated before s– .

Which operator has lowest priority in C?

C Operator Precedence and Associativity

Operator	Description
+ –	Addition/subtraction
<< >>	Bitwise shift left, Bitwise shift right
< <= > >=	Relational less than/less than or equal to Relational greater than/greater than or equal to
== !=	Relational is equal to/is not equal to

Which has highest precedence in Java?

In Java, parentheses() and Array subscript[] have the highest precedence in Java. For example, Addition and Subtraction have higher precedence than the Left shift and Right shift operators.

What is a B in Java?

The Arithmetic Operators Adds values on either side of the operator. A + B will give 30. – (Subtraction) Subtracts right-hand operand from left-hand operand. A – B will give -10.

What is rule of precedence?

In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that reflect conventions about which procedures to perform first in order to evaluate a given mathematical expression.

Does Java read left to right?

Java does not read left to right only. Once Java hits the open parenthesis of the function call, it then expects an expression. It triggers an “expression reading” mode, which for numbers will follow BIDMAS and not read left to right.

What does == mean in Java?

equality operator

Is there Pemdas in Java?

Yes, Java follows the standard arithmetic order of operations. This is because the value 1/4 is evaluated using integer arithmetic, because both the 1 and the 4 are integers. The result of 1/4 in integer arithmetic is 0. To ask the compiler to evaluate this using floating point, use something like 1.0/4.0 .

Is left associative?

For example, subtraction and division, as used in conventional math notation, are inherently left-associative. Addition and multiplication, by contrast, are both left and right associative.

Is left or right associative?

Left-associative operators of the same precedence are evaluated in order from left to right. For example, addition and subtraction have the same precedence and they are left-associative. Right-associative operators of the same precedence are evaluated in order from right to left.
